I have nerve blocks for my feet/ankles/legs. Since Sept/2010 I've had 5 or 6. Mine didn't start for 10 months after my injury, so the series thing wasn't an option, but I do get one about every two months in winter and in summer they last longer. But even though they reduce my pain levels, I'm still not able to function like I did before my accident.

And nope, you can't get two areas at one time. Disappointing I know. You must wait at least 2 weeks between injections, as least that is what I understand. If your feet are really bothering you, do you do epsom soaks. Those totally help me, and actually they provide the most relief I get, at least as long as my feet are in the water. 1/2 cup epsom salts in a dishpan of warm water, heaven!
